ELECTRIC-CONDUIT FITTING AND ELECTRICAL APPLIANCE.

Application filed October 28, 1911.

To all whom it may concern Be it known that we, CARL H. BISSELL, of Syracuse, in the county of Onondaga and State of New York, and DANIEL C. GIDLEY, of Boston, in the county of Suffolk and State of Massachusetts, have invented a certain new and useful Electric-Conduit Fitting and Electrical Appliance, of which the following is a specification.

This invention'has for its object the production of an electric conduit fitting and an electrical appliance therefor; and it consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

- Figure 1 is a vertical sectional view of a preferable embodiment of our invention. Fig. 2 is a plan of parts seen in Fig. 1, the wires connected to the electrical appliance being also shown, and the cap of such appliance being omitted. Fig. 3 is a side elevation, partly broken away, of the cap of the electrical appliance. Figs. 4: and 5 are, respectively, a sectional view and an inverted plan of the cap. Fig. 6 is a detail view of one form of support or bridge for the electrical appliance. Fig. 7 is a detail view of another form of such support or bridge. I

1 is the hollow body of the electric conduit fitting, the body having an opening 2 for an electrical appliance carried by the body, said body also having one or more means as internally threaded nipples 3, by which connection is made with the conduits inclosing the electric wires. The opening 2 is located in the side of the body opposite to the bottom of or side thereof engaging a wall or other structure.

In the illustrated embodiment of our in vention the body is shown as cylindrical at its bottom or base, and the opening 2 is elliptical; and the sides of the body are shown as gradually converging toward the edge l around said opening 2.

5 is a support for the electrical appliance,

said support being secured at diametrically opposite sides of the opening to the body, and extending in a direction crosswise of the opening, the intermediate portion thereof being provided with resilient means for de tachably clamping the base of the electrical appliance.

In the illustrated embodiment of our in vention, the support is in the form of a bridge formed of a strip of sheet metal, opposite ends of the bridge being formed with lugs 6 and the intermediate portion thereof being depressed into the fitting and including side and bottom parts 7 and 8. As here shown the lugs 6 engage the outer sides of inwardly extending ears 9 provided on the fitting at the opposite ends of the elliptical opening 2, the lugs 6 being secured to the ears 9 as hereinafter described.

10 is the base of the electrical appliance, here shown as a lamp socket, and 11 is the cap thereof. The base 10 extends into the fitting through the opening 2 and fits the depressed intermediate, resilient portion of the bridge 5, and is detachably clamped thereto. As here shown, the intermediate portion of the bridge 5, and the base 10 are formed with interlocking means in the form of interfitting projections 12 at opposite ends of the base and depressions 13 in the side portions 7 of the resilient portion of the bridge, the projections and surfaces of the depression having inclined engaging faces, which facilitate the engagement and disengagement of the base and its support. As seen in Fig. 7 the bridge may be formed with spring tongues 1i for entering corresponding sockets in the base. Preferably the bridge is arranged in a groove 15 formed in the bottom and ends of the base. The base is thus secured to the bridge 5 without the use of fastening devices as screws, etc. The base 10 is provided with terminals 16 and 17 which are connected respectively to the central and sleeve terminals 18 and 19 of the electrical appliance, and which extend on opposite sides of the base and are provided with binding devices as screws 20 and 21 on opposite sides of such base. The

central terminal 18 is a light strip having substantially duplicate end portions and a slotted intermediate part. s end portion is secured between the end of terminal 16 and a lug 10 projecting axially from the base 10. and the other eid portion is free and spaced apart from the first-named end portion. The slot 18 in the intermediate portion accommodates 16 end of the terminal 16.

The cap 11 is formed with a base portion 2:2 elliptical in general outline and with a cent al sleeve portion which incloses, in the ordinary manner, l sleeve terminal 19 of L1G the electrical appliance. lhe base portion 22 is formed with a mar inal flange 23, the inner sur' ace 01" which is opposed to the edge el around the opening it, and with shields 24: which extend into the opening 2 between the opposing sides or the base and the sides the body 1, and protect the binding devices and 21. These shields 2% are elliptieally curred corresponding to the curvature of the sides of the opening 9 and preferably the end edge 25 thereof con err'e \J downwardly toward the bottom edges leaving the ends of the base exposed so that the wires, as can pass w the binding devices 20 The cap 11 means screw thereon saic bridge 5 in notches '29 in port 5, spring" at cap and the ba said springs 1 ears 9; :rd coiled springs having cor-res; ing into seats inner face of the ca) bearing against the lu ing gasket is interno ed bet WGcll 23 and the edge 4; o. the springs 31 permit clampin cap 11 relatively to th base the gasket sulliciently "0 term cap is then placed in position a secured in position by turning screws. Owing to the c :torth, the assembly of the part the fitting as provided with four nipples for connection with electric conduits, and the tires passing through two and such nipples only are connected to the electrical appliance. Wires passing through the other two nipples would pass entirely through the litting, and owing to the me; ns of supporting the base oil the electrical appliance, ample space is provided for the passage of such wires between the base and the bottom of the fitting.
